该中间体在本合成路线中的序号：(XLIV)

The reaction of (XLII) with methanesulfonyl chloride and Et3N in THF gives the mixed anhydride (XLIII), which is treated with diazomethane in ethyl ether/THF to yield the diazoketone (XLIV). The rearrangement of (XLIV) with Ag2O in DMF/water affords the acetic acid derivative (XLV), which is condensed with indoline (XLVI) by means of EDC and DMAP in dichloromethane to provide the acyl indoline (XLVII). The desilylation of (XLVII) with TFA/water in dichloromethane gives the secondary alcohol (XLVIII), which is oxidized with DMP in dichloromethane to yield the corresponding ketonic compound (XLIX). The dehydrogenation of the indoline group of (XLIX) with chloranil in refluxing toluene affords the corresponding indole derivative (L).

合成路线2

该中间体在本合成路线中的序号：(XLVIII)

The silylation at the remaining OH group of (XLIV) with TBDMS-OTf and lutidine in dichloromethane affords the silyl ether (XLV), which is oxidized at the aldehyde group with NaClO2 in tert-butanol/water giving the carboxylic acid (XLVI). The reaction of (XLVI) with methanesulfonyl chloride and Et3N in THF gives the mixed anhydride (XLVII), which is treated with diazomethane in ethyl ether/THF to yield the diazoketone (XLVIII). The rearrangement of (XLVIII) with Ag2O in DMF/water affords the acetic acid derivative (XLIX), which is condensed with indoline (L) by means of EDC and DMAP in CH2Cl2 to provide the acyl indoline (LI). The desilylation of (LI) with TFA/water in dichloromethane gives the secondary alcohol (LII).
